Why buy Moog from TFS Oleodinamica

TFS Oleodinamica, a Bosch Rexroth Certified Excellence Service Partner since 1997, supplies new and remanufactured Moog components, performs repairs and overhauls on Bosch Rexroth test benches, and integrates Moog servo valves into its custom-designed control units. The dual expertise of Bosch Rexroth and Moog is a rare combination in the Italian market, offered by only a few service centers.

• Repair and overhaul on Bosch Rexroth test benches of Moog D633, D634, D636, D638, D661, D662, D663 servo valves and related series. Disassembly, inspection, replacement of parts, recalibration of zero and hysteresis, final testing with response curve documentation. Typical turnaround time: 5–15 business days.
• Immediate stock on high-turnover part numbers and direct access to the Moog supply chain for rapid delivery throughout Italy.
• Moog ↔ Bosch Rexroth ↔ Atos cross-reference – replacement of D633 servo valves with equivalent Rexroth 4WRPEH or Atos DLHZO models, maintaining ISO 4401 pinout for the retrofitting of existing test benches and presses.
• Custom multi-brand power units – integration of Moog RKP servo valves and pumps with Bosch Rexroth valve blocks, HYDAC or ARGO-HYTOS filters, Emmegi heat exchangers, and Alfagomma hoses for complete precision HPUs.
• Application support – analysis of control requirements, selection of the correct servo valve family based on flow rate, pressure, response frequency, feedback type, and electrical interface (analog, CAN, Profibus, EtherCAT).
• National and international coverage – service and supply for OEMs and industrial maintenance providers throughout Italy and EU exports, complementing the direct Moog Italia network.
